Answer:

p

=

2

(

4

x

+

3

)

+

2

(

x

6

)

or simplified  

p

=

12

x

−

9

Explanation:

By definition the perimeter of an object is the length of all its sides.

Also by definition, for a rectangle the 2 sides of the width are equal and the 2 sides of the length are equal.

Therefore the equation for the perimeter of a rectangle can be written as:

p

=

2

⋅

l

+

2

⋅

w

where  

p

is the perimeter,  

l

is the length and  

w

is the width.

Substituting what was given about the length and width gives the equation:

p

=

2

(

4

x

+

3

)

+

2

(

2

x

−

6

)

Simplifying this equation gives:

p

=

8

x

+

p

=

p

=

2.) y=-3x-1 and if you look closely you’ll notice the line is going down making it negative and it’s going down by 3 so it’s -3x and when your looking for y just remember you’re looking for the point that’s on the line of y and here you can see the point is on -1 so there’s your answer.

It is reported that 50% of all computer chips produced are defective. Inspec- tion ensures that only 5% of the chips legally mar
12345 [234]

Answer:

probability of defective  = 0.0545

Probability of a chip to be stolen = 0.0917

Step-by-step explanation:

given data

all computer chips produced are defective = 50%

legally marketed are defective = 5 %

stolen = 1%

solution

we get here probability of defective that is

probability of defective = P ( insepected and defective + stolen and defective)  .........................1

put here value

probability of defective = (1 - 0.01) × 0.05 + 0.01*0.5

probability of defective  = 0.0545

and

So, Probability of a chip to be stolen given defective  =P (stolen and defective) ÷ P(defective)           ......................2

put here value

Probability of a chip to be stolen = 0.01 × 0.5 ÷ 0.0545

Probability of a chip to be stolen = 0.0917

Find the volume of a pyramid with a square base, where the side length of the base is 15.9\text{ cm}15.9 cm and the height of th
jeka94

Answer: 1,162.9 cm3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a square pyramid: 1/3 x base area x height

Where

base area = base side length ^2

Replacing with the value given:

Base area = 15.9^2

base area : 252.81 cm2

Back with the volume formula:

V = 1/3 x base area x height

Replacing with the values given and solving for V (volume)

V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters

Feel free to ask for more if needed or if you did not understand something.
